    To mark the 150th anniversary of the chart that has come to symbolize the field of chemistry, 2019 has been declared to be the International Year of the Periodic Table of Chemical Elements by the United Nations. We join the celebrations with a collection of articles that explore elements on — and off — the table.

    Perovskite materials have become very promising candidates for a new generation of potentially printable and efficient optoelectronic devices. Photovoltaic devices based on hybrid perovskites now achieve more than 20% photoconversion efficiency, and applications in solid-state lighting, photodetection and lasing are soaring. Their optoelectronic and photophysical properties are under intense scrutiny. This web-collection brings together a selection of multi-disciplinary research and comments published in the Nature journals that explores the basic properties of halide-based perovskite materials and their potential for application in optoelectronics, from solar cells to lasers. It serves to illustrate the road to easily processable and efficient devices by presenting both historical milestones and the crucial landmark studies published in the last 12 months in the Nature journals.

    Encoded chemical libraries can be used to screen a vast array of compounds against a protein target to identify potent binders. A collection of articles in this focus looks at different methods to create libraries of encoded peptide macrocycles and the advantages that such libraries offer for discovering protein binders.

    Our understanding of the bonding, reactivity and electronic structure of actinides, though it has both fundamental and practical importance, lags behind that of the rest of the periodic table. A collection of articles in this Focus highlights recent developments in this area, in particular featuring uranium(VI) dianions bearing four U–N multiple bonds, berkelium(IV) stabilized in aqueous solution and a plutonium material showing evidence for the delocalization of 5f electrons.

    Extracellular chemical signals that mediate a range of intracellular functions must either be directly transported across cell membranes or be bound to a receptor causing a response to be propagated into the cell interior. A variety of systems have evolved that can operate in this way, but designing synthetic systems that replicate such functions is not trivial. A collection of articles in this Focus discuss artificial methods for transporting chemical information across a lipid bilayer.

    The question of what chemical and physical processes combined to produce the first living systems is perhaps impossible to answer with any certainty, but research continues to provide clues that may help us understand our primordial past. A collection of articles in this Focus explore the origins of RNA and its role in contemporary biological systems, revealing new insights into what early Earth might have looked like and how life first emerged.

    The tissue microenvironment is structurally and dynamically complex. Materials designed to interact with diseased or compromised tissue to induce regeneration, or to act as a scaffold for the production of tissues in the laboratory, thus need to be responsive to the microenvironment. For this, researchers leverage increased knowledge of the importance of the spatiotemporal integration of biomaterials with the tissue environment, as well as latest developments in high-resolution technologies in imaging and in materials synthesis and fabrication. Dynamically responsive materials for use in tissue engineering respond to external stimuli or have inherent properties that trigger the targeted, timed release of integral chemical constituents or of incorporated ligands for the controlled repair or remodelling of surrounding tissue. This collection highlights recent impactful advances, published in Nature-branded journals, in such dynamic biomaterials.

    Nitric oxide (NO) is an important signalling molecule involved in a variety of biological processes, but the way in which it interacts with some metalloproteins is not well understood. A collection of articles in this issue reveals how NO binds to proteins containing type-1 copper sites, based on studies with small-molecule mimics and engineered model proteins.

    Improving the practice of chemistry research and education in the developing world would enable global challenges — such as the need for water and food security, better health, and cleaner energy — to be tackled more effectively by those who are more directly affected by these issues. A collection of articles in this Focus highlight some of the problems faced by researchers in less-developed countries and describe a variety of ways in which local resources can be used in establishing self-sustained research communities that can contribute to chemistry on an international scale.
